The solenoid valves (cartridge types C9 and C13), which can be integrated into a cavity, have a rotationally symmetrical valve housing for the pneumatic ports, air supply and exhaust, and the working connection. Cartridge solenoid valves are available in two diameters: 9 and 13 mm. A soldered circuit board with LED and overvoltage protection is optional. Cartridge solenoid valves switch under power consumption from 0.4 to 1.2 watts. The Cartridge 13 is also available in a particularly energy-efficient bistable version. The following switching functions are standard: 2/2 NC (normally closed), 3/2 NC, 2/2 NO (normally open) and 3/2 NO. Depending on the variant, the pressure range is up to 10 bar.
